Currently, to re-roll properties, you need 1 green dust and 1 blue dust. This system is, in my opinion, unsustainable. I play only legend, with 3 tomes and mostly 2 grims (I might lose one grim when someone dies). Therefor, the lowest chest I get is a soldiers vault. I just dont see any green items. How am I supposed to re-roll my items?
Currently, I personally just dont re-roll properties. My friends either keep a low level char, just to open chests/craft items, or speed run screaming bell on recruit to get a commoners chest and hope to get green item out of them.
Neither of these options are fun, and neither should be needed. Either allow us to downgrade blue dust into green dust, even at a 2/1 exchange rate, or change the item crafting to the way it was in Vermintide 1, where orange items needed only blue dust to re-roll/unlock properties.
